In this paper a 4th order low-pass continuous time analog filter in CMOS 28nm technology is presented. The filter complies with the specifications of the 60GHz next-generation transceivers. A novel circuital topology is presented suitable to perform the low-pass filtering of the in-band signal, while the in-band thermal noise is high-pass filtered, improving Signal-To-Noise-Ratio. 880MHz -3dB bandwidth is obtained by a prototype of the filter simulated in 28nm CMOS technology. The overall power consumption is 4.8mW from a single 1 V supply voltage. 51dB@THD>40dBc is the SNR at 0dB gain.

Abstract
In this paper a 4th order low-pass continuous time analog filter in CMOS 28nm technology is presented. The filter complies with the specifications of the 60GHz next-generation transceivers. A novel circuital topology is presented suitable to perform the low-pass filtering of the in-band signal, while the in-band thermal noise is high-pass filtered, improving Signal-To-Noise-Ratio. 880MHz -3dB bandwidth is obtained by a prototype of the filter simulated in 28nm CMOS technology. The overall power consumption is 4.8mW from a single 1 V supply voltage. 51dB@THD>40dBc is the SNR at 0dB gain.File in questo prodotto:
